I've been using these as my commuting shoes for over a year, and they worked well, and they were good value for the price. They 're true to the scale. US size 9.5 Euro 43.3, ratchet closure and 2 velcro belts. Has iClic pedal compatibility with Look and Time. Used four times. Stiff and sweet, man. Avenir's soles are made of carbon-reinforced fiberglass and woven nylon.
